A common accident scenario was that the platform/skip of a hoist suddenly moved while loading or unloading was in progress erectile dysfunction onset order silagra 100 mg with mastercard. That caused the worker using the hoist to impotence exercises for men silagra 50 mg fall into the hoistway arising from loss of body balance at an unfenced edge erectile dysfunction yahoo answers purchase silagra 50mg on-line, or being trapped by the moving part of the hoist. In recent years, tremendous effort has been made in improving the use of equipment. The design concept is to equip each hoistway gate with interlocking device such that the hoist is operable only when all gates are kept closed. However, past experience had shown that certain hoistway gates were not installed with any interlocking device; or where a hoistway gate had been equipped with an interlocking device, the design and installation of the device was vulnerable to external interference. The most common one was jamming of the interlocking device thereby defeating the purpose of keeping all gates closed before the hoist could operate. For maintenance and repair projects, these problems are very often being overlooked. For some minor scale maintenance jobs, local made makeshift material hoists without any safety considerations should be discouraged. A special guide "Interlocking device on hoistway gates" published by the Labour Department outlines the technical details for their installations. Safety training and communication to the frontline workers are essential in the management of material hoist. Site management should plan and design at the initial stage before any material hoist is installed. After the erection, the equipment should be regularly inspected and maintained by competent persons. Temporary works Temporary works is used to support a permanent structure while it is not self-supporting, such as commonly used in situ concrete, precast units and steelwork, or commonly known as "falsework". This could cause injury or death to those working on or near to it, as well as loss of time and cost. Locally, falsework is commonly used in building construction, maintenance and refurbishment works. A falsework that collapses during dismantling or erection can Construction Site Safety Handbook Page 130 bury workers amidst the wooden formwork and uncured cement. The cause of such accidents could be due to one or a combination of the following: no approved or calculated drawings, the drawings were not carefully prepared, such as neglecting the weather conditions or wind effects of the site, vibration caused by other construction operations nearby and ground conditions, the falsework was not erected by a competent person, erection or dismantling was not supervised by a competent person, the falsework was not checked by a competent person before being used, the falsework was illegally altered, overload of the falsework by unintended loads or unauthorized jobs by other subcontractors, the falsework was not regularly checked and maintained, no safe system of work Another reference document "Code of Practice for Metal Scaffolding Safety", also published by the Labour Department in August, 2001, provides detailed practical guidelines on falsework safety for the building industry.

However, it is still extensively used by workers involved in maintenance and interior decoration jobs, including technicians engaged in water, electricity and gas works, etc. In a typical fatal case, a worker was assigned by his employer to repair a ceiling light flushed into a metal grid of the false ceiling. While he was inspecting the wiring above the false ceiling, he might have come into contact with the earthed metal casing of the light box. Possible live conductor might have come from the faulty earthed metal light box casing, or from some faulty electric wirings above the false ceiling. After careful examination, the aluminum ladder might have been energized by a faulty electric wire on the floor, near Construction Site Safety Handbook Page 137 one of the footings of the ladder. To complete the circuit, current was passed onto the ladder, through the body of the worker and to the earthed metal casing of the ceiling light, leading to electrocution.

Erythrocyticantigens,aswellasleukocyteandplateletantigens, can induce maternal immunization by the formation of IgG antibodies. Antibodies to IgG, the only immunoglobulin selectivelytransportedtothefetus,aretransferredfromthematernal circulation to the fetal circulation through the placenta. The mechanismwhereby IgGpassesthroughthe placentahasnot been definitively established. Becauseofthishemolytic process, the normal 45- to 70-day lifespan of the fetal erythrocytesisreduced.

All pregnant Rh-negative women should receive Rh IgG, even if the Rh status of the fetus is unknown, because fetal D antigen is present on fetal erythrocytes as early as 38 days fromconception.

In general erectile dysfunction drugs for heart patients order silagra 50mg fast delivery, antibiotics decrease the length of disease by about 1 day and may be indicated in individuals with fever erectile dysfunction doctor boca raton generic silagra 100mg with visa, fecal leukocytes erectile dysfunction treatment canada generic silagra 100 mg without prescription, bloody diarrhea, symptoms for more than 3 days, or travelers. Elderly the elderly may succumb to any of the aforementioned etiologies of diarrheal disease but, like children, may become ill faster. They may require more aggressive therapy, diagnostic testing, and possibly hospital admission. They may also require more diagnostic studies including stool ova and parasites and stool cultures. Other agents Other symptomatic treatments include antimotility agents and bismuth subsalicylate (Table 17. Fortunately, this disease process is self-limited and usually resolves in a few days requiring only a short course of antibiotics and/or symptomatic therapy. These include raw fruits, caffeine (increases motility), milk or lactose-containing products, and sorbitol (increases the osmotic load). Disposition Special patients While most diarrheal illnesses are self-limited and otherwise benign, special care needs to be taken with certain patients. Individuals who are immunocompromised, elderly, have multiple co-morbidites, and children may have less reserve to withstand even minor fluid, electrolyte, hematologic, or hemodynamic abnormalities. They should be instructed to drink clear fluids containing some sugar and a eat simple diet. Patients should be instructed to use strict hand-washing, limit unnecessary contacts. Patients who have persistently abnormal vital signs, continued nausea, vomiting, or copious stool output should be considered for admission for hydration, observation, and other therapies such as antibiotics. This can be assessed historically by determining changes in urine output, oral intake, and the number of wet diapers. The majority of diarrheal illnesses in children are of viral origin, with rotavirus accounting for up to 50% of cases. Focus the history to include recent travel, medications, co-morbid disease(s), and associated symptoms. Disease severity should be assessed based on the vital signs and physical examination. Grossly bloody diarrhea is almost always from invasive bacteria and not viral pathogens. Laboratory and radiographic studies are rarely warranted for patients with diarrhea unless dictated by physical findings (hypotension, tachycardia, severe dehydration, mental status changes). The use of antidiarrheal agents should not be pursued for symptomatic relief because they may precipitate toxic megacolon. Evaluating the dizzy patient can be challenging, since it is a nonspecific symptom and is difficult to objectively measure. Although most cases are usually benign, emergency physicians need to be wary about life-threatening causes of dizziness, such as cardiac dysrhythmias and cerebrovascular events. It is important to realize, however, that a person may describe more than one subtype, but rarely will describe elements of all four. Associated nausea or vomiting Vertigo Vertigo is defined as an illusion of motion. Vertigo occurs when there is a mismatch of information from two or more of these systems. Central vertigo indicates involvement of the cerebellum or the vestibular nuclei within the pons and medulla. Movement of the head causes these otoliths to inappropriately trigger receptors in the semicircular canal, causing the sensation of vertigo. There are many things that can interfere Primary Complaints 241 with this reflex, such as orthostatic hypotension, cardiac disease, vasovagal syndrome, hyperventilation, and environmental factors. When this neural reflex fails, pallor, nausea, rubbery legs, diaphoresis, and constriction of the visual fields occur. If the person is unable to lie down, he may progress from near-syncope to syncope. If this still does not cause him to lie horizontally, the body will make antigravity postures that may be misinterpreted as a seizure. Their exaggeration of reactions to normal changes often induces great psychologic stress, including hyperventilation. In reality, their symptoms are actually quite mild, and anxiety is felt to be the sine qua non of psychophysiologic dizziness.

All patients in whom moderate to severe respiratory compromise is either observed or anticipated require admission to an intensive care unit. Others with the potential for respiratory compromise should be admitted and adequately monitored. As a general rule, patients with a new diagnosis of an acute cause of motor weakness should probably be admitted for observation and education. If urgent neurology consultation and prompt follow-up are available, less severe cases may be sent home if the patient and family members are comfortable with this arrangement. However, discharge home should only be considered in cases where rapid progression of disease is unlikely and only after thorough patient education has occurred. Rehabilitation efforts should be initiated as early as possible, and special attention should be given to watch for signs of depression, a significant co-morbidity of ischemic stroke. Some patients may be able to be discharged home after a short hospital stay, but many require extended care in rehabilitation facilities.

Occupational exposures in the emergency department 669 41 Child abuse, elder abuse, intimate partner violence Carolyn J. Emergency physicians treat both victims and perpetrators of violence, often on a daily basis. Emergency physicians are in a unique position to identify abusive situations before they result in permanent physical or psychologic disability or death. Recognition of victimized individuals often requires a high degree of examiner suspicion. Although physical injuries may be the presenting complaint of many abused patients, these victims (or their caretakers) rarely disclose the true mechanism of injury. Caretakers may not disclose the abuse because they themselves are the abusers, or because they are unaware of the abuse by another person. Furthermore, the majority of reported cases of child and elder abuse involve neglect, which may present with medical problems resulting from poor nutrition, poor hygiene, or lack of needed medications and care. Elder neglect is defined as the refusal or failure of a caregiver to fulfill his or her obligations or duties to an elderly person, including (but not limited to) providing food, clothing, medicine, shelter, supervision, medical care, and services that a prudent person would deem essential for the well-being of another. Intimate partner violence is defined as a pattern of assault or coercive behavior of one intimate partner by the other, including physical, sexual, and psychologic abuse.

The term "5-S" comes from a formal system created by the Japanese and adapted by many companies in Hong Kong. It is a set of principles and methodology of organization and standardization that goes well beyond normal housekeeping programmes, and sets Construction Site Safety Handbook Page 45 the foundation for upkeeping and improving the work environment. All parties concerned, in particular the contractors, accepted its importance and usefulness in assigning responsibilities for their operation by reminding workers of the value of exercise and preparedness of risks at the beginning of each shift in the worksite. Under this arrangement, the related subcontractors are required to assemble their employees before the start of work every day and make safety and health arrangements concerning the following matter: Providing instructions to related workers concerning the work contents, working procedures, points concerning industrial accident prevention, etc. Announcing the results of liaison and coordination arrangements between work assignments. Understanding the views and opinions of related workers in the prevention of industrial accidents.

Pediatric Pediatric patients, like the elderly, often cannot localize pathology via an adequate history. When obtaining urine samples via bladder instrumentation, it is advised to send off a culture to ensure proper treatment when follow-up is arranged. Following a single infection in a high-risk pediatric patient, many authors recommend outpatient urologic imaging to identify possible anatomic anomalies, so prompt follow-up is crucial. Immune compromised There are several important points to remember when clinicians encounter an immunocompromised patient. Negative dipstick analysis carries a 5% chance of abnormal urinary sediment on Primary Complaints 553 microscopy. Though nephrolithiasis is a common clinical diagnosis, resist the temptation to discharge the patient without an analysis of the urine. An infection in the presence of obstruction is a true urologic emergency, often called "pus under pressure. Cost-effective emergency care should be a goal of all clinicians, but the total elimination of urine cultures should not be part of this goal. Culture the high-risk patient (immunocompromised, elderly, infants, and pregnant) as well as those patients with prior treatment failures. Though quinolones are increasingly being utilized as excellent monotherapy in urologic infections, clinicians must consider quinolone-related drug interactions, especially when prescribing these medications to the elderly.

Threatened miscarriage occurs in 20­30% of all pregnancies, and up to 50% of those threatened will go on to spontaneously abort. Septic abortions and gestational trophoblastic disease must also be considered in the differential diagnosis of vaginal bleeding in a pregnant woman, accounting for 0. Second- and third-trimester bleeding and postpartum vaginal bleeding are not discussed in this chapter because these patients are routinely evaluated in labor and delivery areas and infrequently cared for by emergency physicians. Prior to menarche or following menopause, any uterine bleeding is considered abnormal. Pathophysiology Physiology of menstruation Normal menstrual bleeding results from the cyclical withdrawal of estrogens and progesterone that occurs, on average, 14 days following ovulation in the absence of pregnancy (Figure 38. Flow is usually heaviest in the first 2­3 days and tapers to spotting in the last 2­3 days. The normal volume of blood lost in a single menses averages 30­40 ml; 80 ml is considered excessive. For the typical woman of reproductive age, depletion of iron stores occurs when monthly blood loss exceeds 60 ml. Menses are normally predictable, with a cycle (first day of one menses to the first day of the next) that ranges from 21 to 35 days. The regulation of menses is dependent upon a number of hormonal factors that result in the process of ovulation. If ovulation does not occur, as in anovulation associated with polycystic ovarian syndrome, the endometrium is exposed solely to the proliferative effects of unopposed estrogen. This endometrium will eventually build to the point of instability and result in heavy, asynchronous bleeding, termed metrorrhagia. These hormones exert profound effects on the endometrium causing it to be receptive to implantation for a short period of time. The endometrium is unique in that platelets have relatively little role in the process Primary Complaints 555 Vaginal bleeding 556 Anterior pituitary hormones Folliclestimulating hormone Leutinizing hormone Progesterone Ovarian hormones Estradiol Ovulation Follicle Ovary Recruitment Selection Uterine endometrium Corpus luteum Corpus albicans Dominance Recruitment 2 Menses 4 6 8 10 12 14 16 18 20 22 24 26 28 2 Follicular phase Luteal phase Menses Figure 38. Instead, endometrial hemostasis relies first upon the presence of local vasoconstrictors, then on factors of the extrinsic and intrinsic clotting cascades that result in the formation of a vascular clot.

Broad-spectrum antibiotics include regimens such as a synthetic penicillin/beta-lactamase inhibitor. Pelvic pain Special patients Pediatric the physician must be diligent to search for a cause of pelvic pain in the young patient. Due to social, cultural and parenteral pressures, these patients and their parents may be scared or embarrassed to answer questions about their sexuality and genitalia, much less undergo a pelvic examination. Any child that is perimenarchal should be assumed pregnant until proven otherwise. Prepubertal children are most likely to present with pelvic pain secondary to vaginal foreign body, urinary tract infection or sexual abuse. A pelvic examination is still indicated in these patients to assess for evidence of abuse. A modified approach can be used, but a full pelvic examination may be required under conscious sedation or general anesthesia. Proper collection of samples and precise documentation are required for evidence if a criminal case is suspected. Most local police departments have developed a sexual assault kit for these purposes. There is also the legal status of the emancipated minor and the mature minor, which varies from state to state. These statutes allow minors certain rights, including seeking and consenting to medical care without the authorization and notification of their parents. Keep in mind that any emergent care deemed necessary should supercede any parental rights. Blood products A blood transfusion is indicated in the patient who is hemodynamically unstable from hemorrhage and unresponsive to crystalloid boluses. A type and screen or crossmatch should be sent for those patients who are resuscitated, or whom you suspect may become unstable. In the situation of fetal­maternal hemorrhage, 300 mcg is given for every 15 ml of fetal red blood cells (or 30 ml of fetal whole blood) that the mother has been exposed to based on Kleihauer­Betke testing. Geriatric the older patient may not be willing or able to communicate her problems. In general, the older patient is relatively immunocompromised and is more likely to have other comorbid problems that can affect the presentation and the work-up. Often, the geriatric Medications Other than analgesics and antibiotics, other medications may be needed to treat the patient. Methotrexate can be 438 Primary Complaints patient will not present with the "classic" symptoms of an acute inflammatory process such as appendicitis or diverticulitis. As a result, the morbidity and mortality of abdomino-pelvic complaints in the elderly patient is significant. The physiologic drop in estrogen levels with age can cause vaginal irritation and thinning of the mucosa. On the other hand, unopposed estrogen levels secondary to decreased progesterone can lead to endometrial hyperplasia and possibly endometrial cancer. Furthermore, the normal ovary should not be palpable 5 years after menopause; any enlargement is abnormal and mandates further investigation. The nonEnglish speaking patient may also be more of a challenge due to cultural issues or anatomic problems. Pelvic pain Disposition Obstetric/gynecologic consultation Ob/Gyn should be consulted for all ectopic pregnancies. Patients also require admission for other significant pelvic infections, uncontrolled pain and inability to tolerate fluids or oral medications. Ob/Gyn should be contacted for a patient with problematic ovarian cysts, follow-up of pelvic infections, any complications of pelvic procedures, and ongoing/threatened miscarriage. The patient may not need to be seen immediately, but input from the Ob/Gyn consultant should be obtained and follow-up arranged. Chemically dependant or impaired Patients who are intoxicated can present with pain that may be overlooked. Their ability to relate a coherent history may likewise present problems for the clinician.

In summary, the test designers want to evaluate your application of clinical knowledge and your ability to communicate well enough to work with other house staff on a joint mission to help keep patients alive and healthy. But precisely how does one demonstrate the ability to manage disease and promote good health by communicating? Rather, its primary objective is to test your ability to apply a fundamental knowledge base by communicating with mock patients toward the goal of extracting enough information to generate a basic differential diagnosis and workup plan. So the best one can do to prepare for the exam is become familiar with its format, practice focused history taking and patient interactions, and present cases in a logical and well-rehearsed fashion. Test designers aim to evaluate your application of clinical knowledge and ability to communicate on a solid level while maintaining a comfortable and professional rapport. To pass the test, all examinees must show that they can speak, understand, and communicate in English as well as take a history and perform a brief physical exam. For quality assurance purposes, a video camera will record all clinical encounters, but the resulting videotapes will not be used for scoring.
